JAMES FLOOKHART, OF NEIVARK, NEW JERSEY, ASSIGNOR OF ONE-HALF TO EDWARDMAHER.

MOLDE'RS FLASK.

SPECIFICATION forming part of Letters Patent No. 501,414, dated July 11,1893.

Application filed March 3, 1891. Serial No. 383,602- (No model.)

T0 at whom it may concern.-

Be it known that I, JAMES FLOOKHART, a citizen of the United States,residing at New ark,in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Molding-Flasks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference bcinghad to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of this invention is to facilitate the operation of castingmetal ingots and to render the same more convenient and easy, moreparticularly in connection with the operation of manipulating the moldflasks, and it consists in the arrangements and combinations of partssubstantially as will be hereinafter set forth and finally embodied .inthe clauses of the claim.

Referring to the accompanying drawings in which like letters indicatecorrespondingparts in each of the several figures, Figure 1 is a plan ofthe improved flask; Fig. 2 a side elevation of the same; Fig. 3 an endview thereof; Fig. 4 an enlarged detail view of a movable tongue adaptedto be employed in holding the flask sections together; Fig. 5 a reducedplan of one of the said sections and Fig. 6 a section of Fig. 5 on lineon.

In said drawings, a and 17 indicate the upper and lower parts orsections which contain the cope and drag of the mold in any ordinarymanner.

0 indicates the handles; e, e, and f, f, side and end clamps,respectively, which hold the sec tions together.

The invention relates more particularly to the novel construction of thesaid clamps. The end clamps, f, consist of sections g, h, bolted to theend boards of the flask, as shown more clearly in Fig. 3,'(and thusremovable therefrom and applicable to other end boards in the event ofbreakage,) and a wedge or key 2' adapted to engage portions of saidbearings and to force the same and the flask sections connectedtherewith into proper relation to receive the molding sand. The endclamp section h, fastened to the lower flask section,

is provided with a broad plate or bearing h to properly engage the flaskand receive the bolts, and a tongue h which projects aboveset toextendout from the flask far enough to clear the section on the other flask.The upper end of said tongue is provided with a lip h which projectsoutward from the vertical line of the tongue to provide, on the underside a bearing for the wedge orkey. The said under bearing may beinclined to correspond and properly coincide with the inclined surfaceof thewedge, as indicated in Fig. 3.

The clamp section, g, secured at the end of the upper flask sectioncomprises a plate g similar to the plate 72/ and serving 'substan tiallythe same purposes, and outwardly projecting lips g 9 arranged to lie atthe opposite sides of the tongues k and below the lips ,h as shown inFig. 3 and provided on their upper sides with bearings for the Wedge t,which latter, when forced in between said lips k and 9 force the sameapart and draw the ends of, the flask sections together as will beunderstood. As both the lips h and g proj ect outwardly from the flasksections, or the broad bearing plates '9', h, the Wedge is exposed moreperfectly to view and can be removed with greater facility. I

The side clamps e, e, are of similar construction, excepting that of thelower clamp'section 6', in which case, the upwardly extending tongue eis made adjustable in relation to the'carrying plate, a of said section6'. The said carrying plate has aloop or eye, 6, thereon slightly belowthe upper edge of the section in which the said tongue slides or movesvertically, so that it may drop from projecting above the margin of theflask section bso as to be out of the way of the workmen when preparingthe mold or be raised so as to pass between the lips or lugs 6 oftheplate 6.

The sliding tongue e at its lower end is provided with bearings, 6 toengage the under side of the eye, e and-at itsupper end with a lip, a toengage the Wedge, e", which lip is preferably inclined on the under sideto properly engage the inclined surface of the said wedge.

In operating the flasks, preparatory to clamping, the sections areplaced together so that the tongues, h which serve as centering dowels,pass between the end lugs g and the sections a, b, are thus brought intoproper coincidence and are fixed by means of the wedges z. The slidingtongues, 6 are then raised so that the wedges, 6 may be interposedbetween the lips e c and thus the sides of the flask section are clampedtogether.

Having thus described the invention, What I claim as new is 1. In aclamp for molders flasks, the combination, with the upper and the lowerflask sections, of a plate secured to the upper section provided withtwo projections, a loop secured to the lower section slightly below theupper edge thereof, a longitudinally movable tongue under the loop,thelower end of Which tongue is provided with a bearing for engaging withthe loop and the upper end is provided with a projection and a Wedge forengaging With the projections on the plate and i on the tongue fordrawing the parts together,

the projection on the upper end of the tongue being adapted to rest uponthe top of the loop when not in use whereby the upper end of the tongueis supported at a point so as not to project above the top of said lowersection, substantially as set forth.

2. The combination with the flask section, a, provided with suitablelips, of a flask section, I), having clamps bolted at the ends and sidesthereof, the end clamps having permanently projecting and lipped tonguesserving as centering dowels and the side clamps having adjustabletongues adapted to be raised to project into holding relation to thelips of the section a and to be lowered to or below the edge of thesection b and suitable wedges substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of JAMES FLOCKHART.

February, 1891.
